It's the early days of Summer in Canterlot City. The university semester is nearing its end, papers are submitted and are being graded, and ponies are enjoying fresh coffee, long days full of sun, and warm nights, restless nights after stressful examinations, ripe for nightmares before the excitement of summer banishes them for a season.

Some dreams refuse to leave the mind upon waking.

EDIT: Cleaned up some grammar and fixed some italics.

EDIT 2: More grammar changes on the advice of EqD.

EDIT 3: Yet more grammatical changes, and some minor detail shifts to improve flow and reduce confusion.
